A VPN is built for privacy on one device: everything goes through one server, and you keep that one address until you switch. A proxy is built for control: you choose which program uses it, which country it exits from, and whether each request gets a new address.
That is why automated work uses proxies. A scraper needs thousands of addresses, an antidetect browser needs a different one per profile, and neither is possible with a single tunnel. A proxy does not add encryption of its own; https sites stay encrypted between you and the site either way.
Questions about proxy and VPN
Is a proxy safer than a VPN?
They protect different things. A VPN encrypts everything leaving your device, which matters on public Wi-Fi. A proxy routes chosen programs through chosen addresses. For privacy on one device a VPN fits; for automation a proxy does.
Can I use a proxy and a VPN together?
Yes. A program can send requests to a proxy while the device is on a VPN. The website sees the proxy's address, and the proxy sees the VPN's.

- A proxy server is a computer that passes your requests on to a website, so the website sees the proxy's IP address and not yours.
- Forward and reverse proxy
- A forward proxy stands in front of visitors and hides them from websites. A reverse proxy stands in front of a website and hides its servers.
- Rotating proxy
- A rotating proxy gives each new connection a different IP address from a pool, so no single address makes enough requests to be noticed.
